The 'main piece 20hasra ledgedgroove 2l into Vwhich thezedge-,of'the screen cloth I8V isreceived, the construction being. suchV that the screen cloth is'stretched` .over arr: outside lip'ZZ andthe edges Il forcedgintothegroove 2|.- The small lpiece or fill'eti I8; having surfaces:which-.are

I show in Figure '7 a sash or frame 28 having a ledge portion 29 theupper surface of which engages the lower edge oi a panel 30 which may beglass, metal, plastic, wood, screen cloth or other desired material. Theupper edge of the panel is engaged by a fillet or strip 3l ofthermoplastic material vone edge of which engages the sash. The fillet3| is then heated and pressed into engagement with the sash and fusedthereto to form an integral sash which grips the edge of the panel 30.

In Figure 8, the sash comprises a lower portion 32 and a cooperatingupper portion 33 having beveled mating surfaces 34 and an edge groove35, in which the edge of panel 36 is received.

The construction shown in Figure 9,is similar to that described andshown in Figure 8 except that the mating surfaces of the pieces 31 and38 are not beveled. So also the construction illustrated in Figure 10 issimilar to the construction shown in Figure 9, except the pieces 39 and40 have a T-shaped groove 4I when assembled. In this groove a readilydeformable filling material can be placed to seal the edge of the panel42.

A suitableV material for the filler is ordinary putty, n

union of the parts is effected by a chemical fusion producedby thesolvent, and it may further be noted `that the term welding applies notonly to the union effected-through the use of solvent, but also to theunion effected by the use of heat.

In Figure 11, I have shown a cross section of a desirable cornerconstruction'for joining the side member or stile Il and the end memberor rail ,|12V of a frame. The ends of each are reduced `in cross sectionand a metal reinforcing plate 43 having holes 44 therein is placedbetween the mating surfacesY at. the corner. Sufficient thermoplasticstock is provided so that when the ends are fused together by pressureand heat the surfaces and edges will all be flush. 'I'his operation canbe performed at the. same time that the screen or panel is being fusedinto position in the sash.V

A frame orvsash, made according to my invention. tightly-and permanentlygrips the Vassociated panel and provides weather-tight joints and astructure having a long life, permanently colored. and of pleasingappearance. The frame can be cheaply and quickly made, and there is nopossibility of any portion working loose.

While I have described certain exemplary embodiments of my invention, itis to be understood that various changes in the arrangement and shape ofthe frame and the methods of making it may be made within the scope ofmy claims.

I claim:

1. A structure of the class described comprising a panel of screen clothhaving its edges ofiset from the plane of the panel body, and asurrounding rigid one-piece frame of organic fused and shapedthermoplastic material embedding and rigidly solidified upon such edgesof the screen cloth and filling the interstices in the embedded edges.

2. A structure of the class described comprising a panel of wire screenand an integral rigid one-piece supporting frame of thermoplasticorganic materiahsaid frame having a ledge portion, said ledge beingfused and rigidly solidified 1 upon and embedding the edges of the wirescreen.

3. In a window comprising a panel and a surrounding frame, a rigidone-piece frame made from sections of thermoplastic organic materialfused and rigidly united to form an edge groove in which thepanel ismarginally received and a sealing groove forming an extension of theedge groove and enclosing a seal in contact with the rim of the panel.

4. .A structure of the class described comprising a panel of wire'screenand an integral supporting frame having a perpherally extending l'edgedgroove in Vwhich and over the ledge of which the edges` of the wirescreen lie, said framebeing formed of thermoplastic material fused andrigidly solidified upon said edges of the screen and within theinterstices therein.

5. A structure of the class described compris- `ing a panel ofv Wirescreen and van integral supporting frame having a peripherally extendingledged groove in which and over vthe ledgeof which the edges lof, theWire screen lie, said frame being formed of thermoplastic materialfusedand 'rigidly solidified upon said edges of the screen and withinthe interstices therein, the plane of the panel being approximatelycoincident with the plane of one of the faces of the frame body.

6. A structure of the class described comprising a frame having a sidemember and an end member formed of plastic material, and a cornerreinforcing element formed of av different material, said members beingat a corner of the frame, fused and rigidly united, .with saidreinforcing 'element embedded in and integrated. with the rate cornerreinforcing element formed of metal, said members being at a corner ofthe frame.

fused and rigidly united with each other and with said perforatereinforcing element, the fused and solidified plastic material fillingthe perforations in the reinforcing element.

`8. A structure of the class described comprising a paneland asurrounding integral' frame formed of a plastic material fused upon theedges of the panel and rigidly solidified, with said edges embeddedinthe plastic material of the frame. said frame having a side member, anend member, and a perforate corner'reinforcing element, said membersbeing at alcorner vof the frame. fused and rigidly united with eachother and with said perforate reinforcing element, theY fused andsolidified plastic material filling the perforaticns in the reinforcingelement.
